Jules discovered this trick in Photoshop while we were editing our underwater images. It’s a shortcut. Command shift L. Hit all three keys at the same time and you autolevel. It punches up color like nobody’s business. Really! It works so often that it is the first thing I do with underwater shots. Suddenly the image has contrast and looks so much better. How? I really don’t understand how the algorithm does its magic. And if you ask Jules, she would faint to speak of a mathematical term. She artistic. Which means she only needs to know the end result and how to do it. How and who figured this all out? Well, it was the good fairy.
